Lyric discussion by Me2 

dave mind is the "world". going halfway around the world is changing you mind 180 degrees. to match the position being in anothers eye.

this song intro "hunger for the greater light"..

if daves mind is the earth and his "hunger is towards the "greater light""..firther the idea.

.the lesser light is the word and the greater light is the spirit.

as dave is the captain of his "world" he aligns his focus of the lesser light "word" and the greater light "spirit" until they are one light. then he knows he is "on course"...

steady as she goes...sticking with daves theological renderings..lining up the "word" (bible) and the " spirit" together as they witness each others light.
